, DAM PER.

SPECIFICATION forming par@ of Letters raten@ No;698,995, dated April 29, 1902.

Application filed J'uljr 13,1901. lerial No. 68,226. (No model.)

To @ZZ whom t may concern:

Be it known that I, EDGAR MILTON MC- CLEARY, a citizen of the United States, residing at Booneville, in the county of Dallas and State of Iowa, have invented new and useful Improvements in Dampers, of which the following is a speciiication. A

This invention relates to stovepipe-dampers; and the primary object thereof is to provide a detachable damper which may be readily interposed between the pipe-'sections Without detracting from the appearance thereof.

With this object in View the invention consists, primarily, in providing a ring into which one end each of two pipe-sections is adapted to t, said ring detachably carrying the damper; and the invention further consists in providing a segmental strip adapted to fit in a corresponding slot in said ring, whereby the damper may be secured in or released from the ring. v

In the drawings, Figure l is a perspective view of the device ready to be applied. Fig. 2 is an end elevation of the same. Fig. 3 is a side elevation of the damper-pintle. Fig. 4 is a detail perspective view of the dampersecuring strip.

Referring to the drawings by numerals of reference, 1 designates a ring of such size asto conform to the standard diameter of pipe and provided with shoulders 2 and 3, formed by a concentric bead 4, cast integral with the ring and positioned intermediate the edges thereof, which alone constitute the stovepipejoint. A semicircular slot 5 is formed in the ring, the ends of said slot and the semicircular openings 5a in the ends of the segmental strip 8 forming bearings for the pintle of the damper, which may be operated by a handle.

8 designates a segmental securing-strip, approximately semicircular and adapted to fit in and close the slot 5, thereby locking the damper 6 in place. In order to prevent accidental displacement of said strip, I provide an eccentric turn-button 9, mounted on the ring 1 adjacent the slot 5, so that it can be turned to project over the strip 8, thereby preventing outward movement thereof.

In assembling the parts it will only be necessary to interpose the ring between the meeting ends of the pipe-sections, and as the ends `will abut against the shoulders 2 and 3 of said ring a tight joint will be made and the inner walls will be unbroken, so as to permit the damper to be readily turned without meeting ing-strip 8, when the damper may be readily removed. As soon as a new damper is in serted or the old one mended it may be readily inserted in place, and by inserting the strip 8 it will be securely fastened without the necessity of taking down the pipe or disturbing the same.

From the foregoing it will readily be seen that I have provided a cheap, durable, and efficient damper, holder, and joint which will readily perform the services for which it is intended.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. In a stovepipe-damper, a ringvprovided with an inwardly-projecting bead and a slot in line with said bead in the ring, in combination with astrip adapted tofiill said slot and project withinthe inner periphery of the "ring, the inner edges 'ofthe strip and the said bead formingshoulders for the meeting edges of two pipe-sections, and bearings formed in the said'ring and strip for a damper.

2.v In a -stovepipe-damper, a ring provided with an inwardly-projecting bead extending substantially half-way around the ring and a slot in line with said bead in the other half of the ring, in combination with a substantially semicircular strip adapted to fill said yslot and project within the inner periphery of the ring to form the complement of the said bead, the ring and strip being so constructed as to form bearings for a damper.

In testimony whereof I affix my signature in presence of two witnesses.
